NOTICE OF CHANGE OF TIME AND LOCATION
OF ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 3, 2020
Dear
Fellow Stockholders:
Because of continued public health concerns about the coronavirus (COVID-19) pandemic,
NOTICE IS HEREBY GIVEN that the Board of Directors (the Board) of Devon Energy Corporation (Devon or the Company) has determined to change the location of our 2020 Annual Meeting of Stockholders (Annual
Meeting) from an in-person meeting to a virtual-only meeting. The Annual Meeting will no longer be held at the Devon Energy Center Auditorium, 333 W. Sheridan Avenue, Oklahoma City, Oklahoma 73102, but
rather will be held virtually, with attendance via the Internet. You will not be able to attend the Annual Meeting in person as the Devon Energy Center, which closed to the public on March 12, 2020, remains closed to the public until further
notice. As previously announced, the Annual Meeting will be held on Wednesday, June 3, 2020, however, the time of the Annual Meeting will be 1:00 p.m. Central Time instead of the originally announced time of 8:00 a.m. Central Time.
We have designed the format of the Annual Meeting to ensure that stockholders are afforded the same rights and opportunities to participate as they would at an
in-person meeting, using online tools to ensure stockholder access and participation.
As described in the proxy
statement made available in connection with the Annual Meeting, you are entitled to attend and vote at the Annual Meeting if you held shares as of the close of business on April 6, 2020, the record date designated by the Board for the Annual
Meeting, or if you hold a legal proxy for the meeting provided by your broker, bank or other nominee.

virtual Annual Meeting, you will need to log in to www.virtualshareholdermeeting.com/DVN2020 using the control number on your proxy card, voting instruction form or Notice of Internet Availability of Proxy Materials. The Annual Meeting will begin

begin at 12:45 p.m. Central Time.
